Document Type and Number:

Japanese Patent JP7202107

Kind Code:

B2

Abstract:

To provide an electrochemical cell stack capable of reducing eccentricity of a fuel gas or air supplied to each of cells without changing an installation area, a fuel cell and an electrolysis device.SOLUTION: An electrochemical cell stack comprises: a laminate in which cells and separators are alternately laminated and in which a side face of the cell is enclosed by the separator; a manifold disposed on an end face of the laminate and including a fuel introduction part for introducing a fuel gas from the outside and an air introduction part for introducing air from the outside; a fuel supply channel which is a channel for the fuel gas to be supplied to the cells and extends from the fuel introduction part through the separators in a lamination direction of the separators; and an air supply channel which is a channel for the air to be supplied to the cells and extends from the air introduction parts through the separators in a lamination direction of the separators. The cells form multiple cell groups in its lamination direction and at least any one of the fuel supply channel and the air supply channel is provided for each of the cell groups.SELECTED DRAWING: Figure 2
